The nanotip includes a base and an apex, the apex having a diameter smaller than a diameter of the base. The method also includes irradiating the nanotip with laser fluence to establish a temperature gradient in the nanotip along a direction from the apex to the base of the nanotip such that the apex and base are etched at different rates.

Abstract: In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc., into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.

Abstract: An example method includes receiving a request for a cloud capability set during an Internet Key Exchange negotiation associated with a virtual private network (VPN) tunnel between a subscriber and a cloud, wherein the cloud capability set comprises one or more cloud capabilities, mapping the request to one or more cryptographic modules that can support the cloud capability set, and offloading the VPN tunnel to the one or more cryptographic modules. The request can be an Internet Security Association and Key Management Protocol (ISAKMP) packet listing the one or more cloud capabilities in a private payload. The method may further include splitting the VPN tunnel between the cryptographic modules if no single cryptographic module can support substantially all the cloud capabilities in the cloud capability set. In some embodiments, the request is compared with a service catalog comprising authorized cloud capabilities.

Abstract: In an embodiment, a care-of address associated with a first node coupled to a communications network via an access node is received. The care-of address may be contained in a notification message sent by a home agent associated with the first node or by a binding update message sent by the first agent. The access node is identified using the care-of address. A request to tap communications associated with the first node at the access node is generated and the request is forwarded to the access node to cause communications associated with the first node to be tapped at the access node.

Abstract: Apparatus, methods and computer programs enable carrying service insertion architecture data plane packets in IPv4 or IPv6 networks by packaging destination addresses using IPv6 mechanisms. For example, a data processing apparatus is configured for receiving, from a service broker, a service label and an Internet Protocol version 6 (IPv6) address of a first service node; receiving an IPv4 packet requesting a service associated with the first service node; creating an IPv6 packet comprising a service label in a Flow Label field of the IPv6 packet, the IPv6 address of the first service node in a destination address field of the IPv6 packet, and the IPv4 packet in a payload field of the IPv6 packet; forwarding the IPv6 packet to the first service node. Approaches allow service insertion architecture support for all-IPv6 traffic including tunneled and non-tunneled techniques for environments in which user applications place data in the flow label field.

Abstract: In one embodiment, a network device joins a first multicast tree to receive post-ad-inserted video content. The network device also joins a second multicast tree to receive the pre-ad-inserted video content. The content from the first multicast tree is forwarded by the network device to the receiver(s). The network device determines if it does not receive the content on the first multicast tree due to any failure, in which case, it delivers the content from the second multicast tree to the receiver(s). This enables the receiver to receive the original (pre-ad-inserted) content during the failure in first multicast tree. When the failure is resolved, the network device can go back to sending the content from the first multicast tree to the receiver(s).

Abstract: Apparatus, methods, and other embodiments associated with providing service insertion architecture (SIA) differentiated services in a virtual private network (VPN) environment are described. Embodiments may provision an authentication, authorization, and accounting (AAA) server with user-to-SIA service-context mapping information. With the AAA server provisioned, embodiments may acquire, in an IPSec VPN hub, during IPSec tunnel user authentication, from the AAA server, the user-to-SIA service-context mapping information. With the mapping information available, embodiments may dynamically map an SIA service to an IPSec VPN tunnel user based on the service information acquired from the Service Broker or Pseudo-Service Broker.

In one embodiment, a method includes determining when a node that is tapped by a first mediation device has moved from a first domain associated with the first mediation device into a second domain associated with a second mediation device. A first packet is sent to the second mediation device if the node has moved. The first packet provides an indication that the second mediation device is to tap the node. The method also includes opening a call data channel to the second mediation device, and receiving information from the second mediation device on the call data channel that is obtained by the second mediation device from the node. Finally, the method includes providing the information to the first mediation device.
